taken with all I/O as inputs, either pulled high or low. That is, there are no floating inputs, nor are
any pins driving an output (with a load).
The I
the DCS (Data Collection System). The DCS accurately reflects the device and specified com-
ponent values, that is, it does not add stray capacitance or current.
For the RC measurement, the DCS selects a resistor and capacitor value, and then varies the
voltage over the specified range. As the voltage is changed, the frequency of operation changes.
For a fixed RC, as V
has been taken, the RC value is changed and the measurements are taken again. Each point on
the graph corresponds to a device voltage, resistor value (R), and capacitor value (C).
